Question

How will you manage GDM?

Hint:

Insulin is the gold standard for treating GDM when lifestyle changes are insufficient, and close monitoring is required for both maternal and fetal well-being.

Answer 1

Step 1: Initial Approach to Management.
The management of gestational diabetes involves lifestyle modifications, glucose monitoring, and, if necessary, medication to control blood glucose levels.
Step 2: Lifestyle Modifications.
(1) Dietary Management:
- The patient should be referred to a dietitian to create a balanced, low-glycemic, nutrient-dense diet. This helps maintain stable blood sugar levels.
- Emphasize small, frequent meals to avoid large blood sugar spikes.
(2) Exercise:
- Encourage moderate physical activity, such as walking or swimming, for at least 30 minutes most days of the week. Regular exercise can help regulate blood glucose levels.
(3) Weight Management:
- Instruct the patient to aim for appropriate weight gain during pregnancy (usually 11-20 pounds for women with normal BMI) to reduce the risk of complications.
Step 3: Blood Glucose Monitoring.
- Self-monitoring of blood glucose (SMBG) is essential to track glucose levels. The patient should check fasting blood glucose levels and 1-hour postprandial glucose levels.
Step 4: Medical Management.
(1) Insulin Therapy:
- Insulin is the preferred treatment for women who cannot control blood glucose through diet and exercise alone. It is safe for both mother and baby.
- The starting dose of insulin is usually 0.7-1.0 units/kg/day, adjusted based on the patient's blood glucose levels.
- Insulin is typically administered in the form of long-acting insulin (basal insulin) and short-acting insulin (prandial insulin) to maintain optimal glucose levels.
(2) Oral Hypoglycemic Agents:
- Metformin and Glyburide are oral medications used in some cases. These may be prescribed if the patient is insulin-resistant or prefers oral treatment, although insulin remains the gold standard.
(3) Fetal Monitoring:
- Regular ultrasounds to monitor fetal growth and check for signs of macrosomia.
- Non-stress tests and biophysical profiles can be done to assess fetal well-being, especially in the later stages of pregnancy.
Step 5: Postpartum Care.
- Follow-up glucose testing is recommended 6 weeks postpartum to screen for type 2 diabetes, as women with a history of GDM are at a higher risk.
- Women should be counseled on lifestyle modifications to reduce the risk of future diabetes.
